Grew up a 'Trekkie' with Classic yet liked less than half the episodes. Kept with it because the characters were wonderful and let me not get started on the tech. Watched TNG....liked less than half the episodes...especially after the Federation conspiracy plot lines started. Fan for same reasons as Classic. Watched DS9 and loved nigh everything. Voyager and Enterprise....yawn. Gave up less than a season in. I like my space adventures to be the kind that make you want to go out there and explore...rather than the ones that make you want to shoot E.T. 'just in case' its another 'Alien'.
Star Trek appealed to me back in the 60's because it was so hopeful and at times sheer fun. (Piece of the Action/Trouble With Tribbles)
